Answer:

B-Neither ordered pair is a solution.

Step-by-step explanation:

<h3>Given</h3>

<u>Equation </u>

6x−y^2=14

<u>Ordered pairs </u>

(−9,3) and (2,−4)

<h3>Verifying pairs</h3>

(−9,3)

6(-9) - 3^2 = 14
-54 - 9 = 14
-63 = 14
Incorrect

(2,−4)

6(2) - (-4)^2 = 14
12 - 16 = 14
-4 = 14
Incorrect

Correct option is B

Answer:

$\frac{1}{16}$ $\frac{10}{9}$

Step-by-step explanation:

a reciprocal is a number that when multiplied by a given number gives 1 as product.

16 * x = 1

x = 1/16

9/10 * x = 1

x = 10/9

9/10 and -9/10 determine if parallel, perpendicular, or neither

irakobra [83]

Parallel means the slopes are the same
Perpendicular means they have opposite reciprocal slopes.

We can apply these concepts to this question. Although they are opposites of each other, they are not reciprocals.

So, the answer is neither

Hope this helps!

Being 10 miles apart, two cars started moving towards each other. After one hour they met, and during that time the first car co

Vladimir [108]

The speed of the first car was 6 miles/hour

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

$\large {\boxed {a = \frac{v - u}{t} } }$

$\large {\boxed {d = \frac{v + u}{2}~t } }$

<em>a = acceleration ( m/s² )</em>

<em>v = final velocity ( m/s )</em>

<em>u = initial velocity ( m/s )</em>

<em>t = time taken ( s )</em>

<em>d = distance ( m )</em>

Let us now tackle the problem!

<u>Given:</u>

Distance between two cars = d = 10 miles

Time Taken = t = 1 hour

Distance covered by the first car = d₁ = 2 + d₂

<u>Unknown:</u>

Speed of the first car = v₁ = ?

<u>Solution:</u>

$d = d_1 + d_2$

$10 = ( 2 + d_2 ) + d_2$

$10 = 2 + 2d_2$

$10 - 2 = 2 d_2$

$8 = 2 d_2$

$d_2 = 8 \div 2$

$d_2 = 4 \texttt{ miles}$

$\texttt{ }$

$d_1 = 2 + d_2 = 2 + 4 = 6 \texttt{ miles}$

$v_1 = d_1 \div t = 6 \div 1 = 6 \texttt{ miles/hour}$

The winner of an election is voted for by the majority of people. If there are two things being voted for, veggie pizza and chicken, and pizza earns 36% of the vote, then chicken must earn 64% of the vote because 36 and 64 add to 100.

Therefore, the chicken would win the election and be on the lunch menu.
